I would love to see HTTP adopt SRV as well. Sadly the browser vendors think they're important enough that they can squat the address record all for themselves.

Last argument I heard in chrome bugtracker it was - doing additional dns lookup slowdown user experience, which is why they abandoned idea adding it

That is what we call in Australia a "furphy". SRV records do not intrinsically require an additional lookup or round trip. Poor zone configurations may fare less well. But that is true of all poor DNS configuration. For sites that care about resolution speed, they already optimise as necessary, and they would for SRV as well.
Browsers do not own the A record and should never have been using it in the first place, so to continue squatting them and invent specious reasons for doing so is simple arrogance and assertion of unwarranted privilege.
Instead we have the multiple warts and misbehaviours of misusing the DNS for URL endpoint resolution.
