I tried to deprecate the stabs support a little over 4 years ago.

There was a suggestion to change the error to a warning, but my startup
company job kept me so busy I never had a chance to follow up on this.
I would like to see the stabs support deprecated and the later removed from
gcc. No new features have been added in a long time, and it is only being
maintained in the sense that when it fails it is fixed to ignore source
code constructs that it doesn't support. The longer it survives in this
state, the less useful it becomes.
