You're not getting it, are you? The roadmaps of Bitcoin, Bitcoin Cash, Monero, Litecoin and so on are not determined by just the users, but by the developers. People decide which protocols to join according to the available options and roadmaps. You cannot force a developer implement what you have got in your head. The developer is free to write any code he/she wants and you can do nothing about it other than not running it.
you sound too much like doomad, infact i think you are doomads alt account that its too similar to not be doomad
what you dont get is that core can code things, BUT bitcoins consensus was hard where it required the network of USERS to be ready to understand a new features rules and format BEFORE the feature would activate. thus years ago core had to propose things and get users onside to want to upgrade and be ready to THEN activate
however things have changed due to the softening of the way things work where by core can now implement stuff without users mass consent (consensus)
because users nodes now dont need to understand new stuff and just let it be accepted into blocks and not reject blocks that have data that nodes do not understand..
things have become softened where it no longer requires a mass of full network nodes to fully validate all bytes of a block...
this trick has allowed core to do things like ad exploits which have caused headaches, congestion and fee peaks and bloat.
and now that all other brands that could have different other proposals outside of cores roadmap, have been REKT before they even got popular on the bitcoin network so no one bothers because they know they will get slammed by an army of cultish idiots screaming at them that they should create an altcoin instead of propose things on the bitcoin network, and how the bitcoin core moderation policy of all discussion platforms and other development has been a closed door to anyone not kissing the core monarchy ring and obeying the core path
learn what consensus did for the network before core softened it.. it will shock you(if you re not doomad) but im starting to think you are too similar in the narratives being verbatim to not be his alt account
