Many [r3_hex_http] ... is deprecated in favour of ... messages during compilation and upgrades

[tothlac]

When I run for example rebar3 upgrade I have many (sometimes hundreds of these messages:

One of these messages would not be disturbing, but having hundreds of them is not nice looking. I was trying to figure out why do I have these, but I could not find the root cause.
Can you help to figure it out?

rebar3 version used : 3.18.0 and 3.22.1

I do not see the same output when running these commands, even on OTP 26.1.2.

However I know our vendored hex dependencies were old, so I bumped the library version in #2838 -- can you see if that helps?

E: it appears the new thing fails on CI but seems to work okay-ish locally, I'll need to debug a few things.
