Currently my solution is separating the profile file into two parts, one
contains PATH and SSL related envs, the second part contains all the
others exported by guix. Then I source the first part in login shell
while the second part in interactive shell.

It's a little hack, which means not the way it should work, to me that's
a problem. Guix is still young, we don't have many legacy problems that
needs hacks to solve. I love guix project, which is elegant from the
choice of scripting language and the underlying functional logic. I hope
that if we be picky enough, Guix can stay this way. So lets eliminate
these hacks. :)

Thanks for your time.
