Sure, you must not enable re-INVITE for peers that you don't know for a 
_fact_ will support it properly. Anything behind a NAT/firewall will be 
prone to problems, and proxies that don't handle re-INVITE properly will 
be problematic as well.

However, if you don't turn it on unless you are sure that device can 
handle it, it works very well and is quite useful. We use it between our 
network of Asterisk servers so that the media takes the shortest path 
possible at all times.
