I don’t know, is this (read-only permission on installed files) a common
problem?

As you can see I’m fairly conservative when it comes to changing (guix
build utils).  :-)

The reason for this is that changing it entails full rebuilds.  Thus,
the approach so far is to try to make the procedures in there fairly
generic (with keyword/optional parameters, etc.) so that they are
applicable to a wide range of use cases.  At the same time, we try to
make changes there only when we’d have to repeat ourselves in package
recipes.  If a problem shows up in just one package, we adjust the
package definition and leave (guix build utils) unchanged.
