The inability to put - on <+... ...+> was a bug.  So I don't know if 
fixing a bug would be considered a sign of an unstable grammar.  There was 
also one deliberate change in the grammar some rc's ago related to the use 
of commas in sequences (parameter lists etc).  But otherwise, the changes 
in the grammar have been additions, as people eg ask for new kinds of 
metavariables.

But Coccinelle is a research prototype under development, not a product.  
So I'm not sure it is appropriate to say that we guarantee anything.
