[Asterisk-Dev] Food for thought in future versions: User-specified tone sequence recognition

Would making dsp.c flexible enough to check and recognize user defined tone
sequences in asterisk channel variables be something which could prove
beneficial for several applications?
I can think of a few:
1. Pager prompt tone detection.
2. Burglar alarm central station receivers.
3. Coin telephone denomination detection.
4. SIT tone detection
5. Unusual/Obscure/Special call progress tone detection.
Looking at the code in dsp.c, things are pretty convoluted at the moment
maybe in the longer term we could rewrite it to allow the addition of
user-defined tone sequences.
