I assume you mean RFC 3630 "Traffic Engineering (TE) Extensions to
OSPF Version 2"? This would be used by providers running MPLS, RSVP-TE
and using OSPF as the IGP.

As far as I can see it is supported by all major vendors. The reason
you don't hear all that much about it is probably that a significant
number of providers running MPLS and RSVP-TE use IS-IS as their IGP
(we do).
