The problem with _install_langs is that there is no easy way to change it
after installation, say you find out you've initially installed just English
and French support, but later you need German and Italian. rpm nor dnf
doesn't offer any easy way to add those missing %lang parts to the installed
packages.
First: situation when someone may need to change set of lang dependent resources is extremely rare.
In other words: Jakub you see the problem where in practice there is no problem.
Second: just checked part of my own procedures adjusting set of installed land dependent resources:
echo "reinstall packages with only necessary locale"
echo "%_install_langs en,pl" > /etc/rpm/macros
rpm --rebuilddb; dnf clean all; df -k /; rpm -qal|grep LC_MESSAGES|xargs rpm -qf 2>&1|sort|uniq|xargs dnf -yq reinstall; rpm --rebuilddb; dnf clean all; df -k /
Probably this can be improved by other rpm db query extracting list of files with lang tags but for me it is GoodEnugh(tm).
Third: reduction of installed lang dependent resources can be done by rpm db query -> extract list of files which needs to be removed -> correct list of installed files -> remove unwanted files. Add such function to existing to existing rpm/dnf (you must probably agree) will be trivial. Isn't it?
Extending set of installed languages support in case of rpm is only possible to do by full download of affected packages and reinstall them or in simplified scenario extract files which needs to be added to installed system image.
In other words .. even this is relatively easy.
And yes .. at the moment only Solaris IPS provides handling above scenarios in simplest possible way because in IPS semantic package exist only as object in remotely accessible repository which each object like file or metadata can be downloaded separately. This solves as well many other rpm issues like existence of rpm noarch package, lack of sharing common files between arch dependent packages and sharing not changing files between packages versions/releases on packages repository side.
