Considering the present circumstances, I would suggest that DBD::SQLite have a 
feature freeze until 1.31 comes out, so that if the present 1.30_04 is found to 
not cause problems, testers can be confident that 1.31 is the same.  And then 
changes such as you suggest can be considered.

Meanwhile, feel free to submit an RT item for this request so it can be better 
tracked.  Including a patch would make it get applied sooner than otherwise.
