I think that's a very good idea, yes please. You'd hope that people using SQL Anywhere, or more specifically dbisql, are competent to be using databases. The autocommit default and this message smacks of what they call the 'nanny state' down here.
I can't help wondering if it would be a reversion rather than an enhancement. In 20+ years using SQLA and various flavours of dbisql I can't recall this message coming out before, and I always turn off autocommit (and fast launcher) immediately after installing the software.
