‘Install’?  That doesn't sound good.  :-)

<https://github.com/The-Powder-Toy/The-Powder-Toy/blob/master/src/client/Client.cpp#L366>.

From my reading, that will embed a store file name into a .desktop 
file somewhere in (each) user's $HOME, which will break sooner or 
later.

Even if I'm wrong and it's ‘safe’, I don't see how this behaviour 
is desirable.  What is upstream trying to accomplish here?  Do you 
see how this would be helpful compared to doing things the 
normally?

If not, I think we have a responsibility towards our users to 
install a copy of the above .desktop file and patch out any 
xdg-desktop-menu calls.  Same for MIME types and icons.

Kind regards,
