There are two important properties the name can tell about
- name
- version

default.nix tells "I'm the default version", but does no longer tell
which version it is

19.nix tells "I'm version 1.9", but does no longer tell that its the
default version - so neither is perfect.

In any case its "redundancy" which should be avoided if possible
cause the default version is not set by filename, but in
all-packages.nix. Using sensible names is good habit always.

That's why I even proposed default-19.nix (which was kind of joke just
to illustrate that both solutions could be accepted).

In the end the name of a .nix file doesn't matter its contents do.

If there are weak pro and cons I'd vote for keeping as is. And thats
what the mail was about - sorry if I didn't talk about this point more
clearly.

Sorry if my mail sounded strong. I want to avoid noise so that we can
focus on things which really matter (such as fixing the ghc-pkg list
output)
