Was the rebar2 --> rebar3 change mostly backwards-compatible, and would
a hypothetical rebar2 or rebar4 build system look mostly the same?
If both hold, I would treat rebar2 --> rebar3 as ‘merely’ a package
update from python@2 to python@3 -- some breaking changes, but no need
for separate build systems (and hence, no 3 suffix)

If rebar2, rebar3 and rebar4 would require completely different phases
and use different file formats or such, IMO a separate build system
(and hence, a 2, 3 or 4 suffix) may be useful.

Greetings,
Maxime.
