You don't strictly need different namespaces even at compile time,

This is a lot easier under Gentoo than in Debian or RedHat or other
binary distros (IMNSHO.)
And while it's not hard to add a PPD or whatever it's called for Debian,
it's exceedingly easy to add a slotted ebuild on Gentoo supporting a new
version of a library that can be installed alongside other versions of
the same library (runtime and compiletime on Gentoo.)
But to each their own.

As can Debian, so I'm a bit surprised. It's straight forward on *nix-like
systems to have multiple run-time versions of a library. It's designed
for it.
The problem is when you need different *compile time* (aka development)
versions of a library, then you'll need to have different name spaces.
The remaining issue may be that the distro may not provide different
versions of all the libraries you need out of the box. Then there will
be additional
work. And that may or may not be more effort than it's worth, granted.

a
specific version of a system library, another program needed a
*different* specific version of the library and the rest of the system
wanting yet a 3rd version of the same library.

After running into that particular package hell early on in my Linux
experience, I switched to Gentoo linux where multiple versions of
libraries can be installed at the same time and used by whatever
software needs them.
