The Concept: Certain weapon slots are only capable of fitting certain sized weaponry.
What does this do for the game?
This creates the ability for the developers to balance each variant of each chassis individually.
Some mechs which are classified by the community as blatantly inferior, could find a new life as variants capable of doing what their counterparts could not.
Weapon Size Classifications: These are my ideal classifications for weaponry.
So if you have a "Light Energy Hardpoint" in your mechs arm, it could only outfit the energy weaponry categorized under the "Light" section. Also, a Mech with, for example, a "Heavy Missile Hardpoint" would be able to outfit Light, Medium, and Heavy Missile weaponry.

For example: the Catapult K2's machine gun ports, with Hardpoint Size restrictions, could not outfit anything larger than what would be considered to fit into a "Light Ballistic Hardpoint".
Let's keep up with the example being the Catapult K2.
The Stock K2's weaponry consists of 2 PPC's, 2 Medium Lasers, 2 Machine Guns.
What we have now is essentially 4 Energy, 2 Ballistic slots capable of fitting all Energy and Ballistic armaments in the game. Which usually means it's run as a 4PPC boat or AC/40 boat.
Not exactly the peak of customization, when given all options, people will just run the most powerful weapons they can, even if the variant they're piloting was absolutely not known to do so within the lore of Battletech.
If the K2 had Hardpoint Sizes, it must coincide with the lore, stock variant of the chassis.
So the K2 would have 2 Heavy Energy Hardpoints, 2 Medium Energy Hardpoints, 2 Light Ballistic Hardpoints.
What does this mean for our precious K2? It becomes the only catapult capable of outfitting PPCs, due to the two very large ear cannons not present on any other variant.
Arguments Against Hardpoint Sizes:
"The game is fine!"
- No it isn't. When the majority of mechs in competitive and high elo play are running exclusively heavy weaponry, you know the game is borked.
"Hardpoint Sizes will kill customization!"
- No they wont. If anything the concept can highlight the use of unused variants. Remember the last time you saw a Stalker 3H, let alone one that performed outstandingly? An Awesome 8V? How about a Commando 3A? Hunchback 4J?
By individually assigning Hardpoint Sizes you can limit the absurd strengths of some mechs (Here's looking at you Stalker 3F) and at the same time boost the capabilities of lesser used variants, even providing each variant of a chassis with a more unique and defined role on the battlefield.
Example: The Stalker 4N. There is literally no reason to take it over any other Stalker.
Through Hardpoint Sizes, a seemingly useless mech like the 4N can be given a unique benefit over its counterparts. The 4N, for example, may be the only Stalker containing 3 Heavy Energy Hardpoints, essentially making it the only Stalker capable of outfitting 3 PPC's. Giving it a unique role amongst the other Stalkers which may only have 2 Heavy Energy Hardpoints.
TL;DR: Read the post you lazy herb.
Also* This would coincide with other gameplay changes, this is not a one size fits all answer.
