Is this a new expected standard? Is that desired?

There is no standard :) There are defaults, and they can be changed ... were they changed? Maybe, some years ago , history not that interesting :)

Everybody is free to configure an install of perl however their like

So your environments should use Config and they won't be surprised 

 $ perl -V:install.+
installarchlib='C:\citrusperl\lib';
installbin='C:\citrusperl\bin';
installhtml1dir='';
installhtml3dir='';
installhtmldir='C:\citrusperl\html';
installhtmlhelpdir='';
installman1dir='';
installman3dir='';
installprefix='C:\citrusperl';
installprefixexp='C:\citrusperl';
installprivlib='C:\citrusperl\lib';
installscript='C:\citrusperl\bin';
installsitearch='C:\citrusperl\site\lib';
installsitebin='C:\citrusperl\site\bin';
installsitehtml1dir='';
installsitehtml3dir='';
installsitelib='C:\citrusperl\site\lib';
installsiteman1dir='';
installsiteman3dir='';
installsitescript='C:\citrusperl\site\bin';
