Seconded.

Tilde expansion is performed by the shell.  In the case of
‘--foo=~/bar’, tilde expansion does not happen because ~ is right in the
middle of a string.

It’s admittedly annoying, but it’s not something Guix itself should
paper over.  Doing that would open a can of worms, as illustrated by the
example Tobias gave.
