Silly question: will the software have ".4" baked into the name (i.e.
PROJ.4 version 10.x), or will it be incremented (i.e. PROJ.10, a
terrible idea), or dropped entirely (i.e. PROJ)? Ideally, I'd advise
future-proofing the name by simply reverting to the original name,
PROJ. Of course, renaming has lots of implications for 3rd party
software that have objects like "proj4text" or "proj4string".

To keep the name permanently as PROJ.4 for any future version, the
meaning of ".4" needs to change to something like 4-dimension
projection capabilities (x, y, z, t).

On a historical note, there never was PROJ.1 from 1980 or PROJ.2 from
1985, or even a PROJ.3 (as documented at the time) from 1990. The name
PROJ.4 first appeared for release 4 around 1994, possibly to help
distinguish from the previous releases.
