The whole idea is, that using Lazarus as an ide, the user actually gets 
to see what is used...

Otherwise, if users have problems, and are asked to tell what they use, 
the don't know.
and there are no docs or other methods to tell what info fpc uses by 
default, on platform xyz (not to speak to need to know the fpc version ...)

So being able to tell what the default is, is full intention.

Also according to testing I have done, using the version of GDB included 
in lazarus => so doing what the average user would do, it appears that 
dwarf is delivering better results. (e.g, (IIRC) properties that map to 
fields are inspectable, if using dwarf => so promoting dwarf, will 
reduce the amount of problems that new users have)
There may of course be exceptions to that. Thats why there is a choice.

Out of curiosity:
- Why do you prefer stabs?
- Why do you prefer stabs generated by -g, rather than choosing explicitly?
