Progressing along the enshitification line nicely.
In this case, I should not have.
The question revolves around reasonableness. You've designed a storage mechanism (inventory) so you have a mechanism in place to limit what players carry. Sure. You've created a stack mechanism to keep like items together in your storage mechanism because people will bitch about having 10 bobby pins taking up all your inventory space. Okay. Now you introduce weight as another limiting factor and slow them down when they already have to make multiple trips...unreasonable.
If you give me inventory space enough to carry 18 metric tons but then make it so I can't move, that's not reasonable. Reasonable would be to limit the number of items I can carry and/or limit inventory item stack sizes.
I have never wished for encumbrance in a game that didn't have it. I've only ever wished it was gone from those that do.
PC gamers have tools to mod games. Mostly. Console players do not have this option. Mostly. While this may not be an issue, for you, does not make this a non-issue.

MTB is downhill mountain biking.

Skyfarer, the Sunless Skies TTRPG, has a strong steampunk aesthetic. I thought I had posted this earlier but maybe not.
If you liked 5e but not a fan of what WotC is doing, I would suggest looking into Level Up: Advanced 5e. They've improved on a lot of things about 5e (e.g. monster stat blocks and challenge ratings) and you can still use your adventures and supplements (with maybe some tweaks).
In general, with as many different rulesets that exist, I would say that offering a bit more of what you want in a TTRPG experience would go a long way in helping people offer suggestions. Example keywords: sci-fi, fantasy, modern, cinematic, tactical, mystery, supernatural, etc.

Aaron A Reed Releases 50 Years of Text Games Portal
I've long been a fan of text adventures (aka interactive fiction) so when I saw that Aaron A. Reed was Kickstarting a book covering 50 years of it, I immediately became a backer. For each year, he selects one text adventure that encapsulates what the state of the genre was like for that year. Well, he's recently released it to his backers in electronic form and has set up a website where everyone can find links to each of the games he covers so they play, download, or buy the game in question. It's definitely worth a look.
I know Steam (Valve) have metrics on it that probably give a good idea of how Linux fares in the PC market for gaming. Probably not entirely accurate but maybe accurate enough. I know it's the best I've ever seen though.
If you're looking for something geared more introductory to co-op board games, Castle Panic is good:
