miners are the "equipment owners" who have invested money in a business called bitcoin mining to make profit. easily replaceable.
developers are knowledgeable programmers maintaining the code, bug fixing, and improving things. since bitcoin is open source they are also replaceable (not easily though).
but bitcoin is what remains. and must prevail. and people are investing in bitcoin because of what they see bitcoin is and what they can do with it, not because they see miners or developers.
I quite agree with you. The good of Bitcoin should prevail above the dev and miners. If there is anything that dissatisfies and grieves me much, it's the slow confirmation and backlog of transactions that have now become second nature to bitcoin.
Whollistically speaking, I think on the other hand that the devs hold the sceptre because without them miners won't have any Bitcoin transactions to process.
