IMHO that's a bit exaggerated (the last line)? I do use plenty of 
watches, and never got any such message. Ok I know I can't see 
properties, and I do not try to do so. That leaves still plenty of ways 
to get information.

Mind, I do NOT want to play down say that the lack of property support.  
Not to break an other war about how serious this is or is not. let 
everyone decide for themself. But to me a statement like the above, is 
simple wrong, as I do use Lazarus+gdb, and in 99% of my personal use 
cases (mostly debugging the IDE itself) it has not caused an issue.
(Personally I thing such over exaggerated statements are made in some 
hope, that making things look worse, would get *others* to fix them => 
another of my experiences says, that does not work at all)

Anyway, I started the topic exactly because I want the situation to be 
improved, and to see what can be done.

yes, a none gdb debugger would be nice, infact it is on the list. but it 
will be a lot of time till then, and even than it will require the debug 
info.
