Unfortunately this does not solve the issue for me personally. I post a 
lot of code in the forum, and since I normally work with Laz-trunk and, 
of course, forget to activate the compatibility option the code will be 
useless for users of legacy versions. I really would appreciate to have 
the previous solution (a global default setting for the compatibility 
option) in addition to the current solution. Of course this new option 
should now be off by default, but after once having switched it on all 
my demo projects would be readable also by legacy Lazarus. I reopened 
bug report https://bugs.freepascal.org/view.php?id=22752 for this request.

 From the perspective of a legacy Laz user a stand-alone tool to convert 
the new format back to legacy would be helpful, too. Currently, a user 
not having Laz trunk is unable to open any projects saved by Laz trunk 
without editing the xml files manually!

Most users still are not aware of this change - see discussion following 
https://forum.lazarus.freepascal.org/index.php/topic,44161.msg316081.html#msg316081. 
I think this is an important point to be listed 
inhttp://wiki.freepascal.org/Lazarus_2.2.0_release_notes.
