~/.recently-used

[Stephan Bergmann]

At least on Linux, LO might write a file ~/.recently-used (containing 
some XML-formatted information about recently opened documents, 
apparently), see 
<https://bugs.documentfoundation.org/show_bug.cgi?id=122114#c2> for details.

That bugzilla comment also argues that that functionality is likely 
unused (at least LO itself never appears to read that file, only write 
it) and could probably be removed.

Does anybody know whether that ~/.recently-used is actually usefuly, and 
we should continue writing it?

(<https://bugs.documentfoundation.org/show_bug.cgi?id=122114> "Fix 
hardcoded location for .recently-used file" about removing that 
functionality has recently been turned into an EasyHack, and I'd like to 
have it clarified here whether removal is actually OK before some 
EasyHacker starts working on it.)
