I see what you mean, I am not sure it is wise to bypass distributions. 
How many software providers do this today?
Even Google with all those resources available has not been able to 
provide one binary for all Linux machines...

We would need to re-invent the wheel in some cases to do this.
But this does not mean I don't like the way you are thinking.

Unfortunately freedom is still an every-day battle.
At least we are winning on the server side.

I know packaging is not perfect today, but is much better than it used 
to be 5 or 10 years back.

This is exactly why this version is not available...

Because GNU/Linux is all about freedom of choice. No matter how we 
decide to create packages, people will want native packages for their 
distribution through UbuntuGIS, DebianGIS, EL, OBS, AUR etc.

I agree that OSGeo4W is a huge project that fits exactly the needs of 
Windows users. I am sure a OSGeo4Mac would also be very successive.

If we had the spare time and I was to make this decision, I would prefer 
offering deb and rpm files for all OSGeo related  projects and I would 
be left with 10 years for vacations :)
