Re "create empty .lproj directories for languages supported by OS X"

I have some questions about 
<https://gerrit.libreoffice.org/plugins/gitiles/core/+/6e9a41dbc25402350e4b767d8f10e8e855f7531a%5E!/> 
"create empty .lproj directories for languages supported by OS X" 
(quoted below; affecting only the non-default test-install make target, 
and only for macOS when configured with --enable-macosx-code-signing):

* What is the reason to still generate those now-empty 
Contents/Resources/*.proj/ directories?

* Since 
<https://gerrit.libreoffice.org/plugins/gitiles/core/+/7a08bfeabe21193e04b9747a831653efcfc63190%5E!/> 
"tdf#122244 Put InfoPlist.strings files at correct places on macOS", at 
least some of those Contents/Resources/*.proj/ directories in 
instset/LibreOffice*.app/ and in corresponding (--with-package-format=*) 
installation sets will contain empty InfoPlist.strings files.  I do not 
know if that is a problem for the --with-package-format=dmg installation 
sets, nor whether it is a problem here for this special 
--enable-macosx-code-signing test-install target.
