Yes.

We created our content assist for jsp files much before the first version
of WTP. It's pretty simple but it was working much better then WTP's one
for long time. Now we don't need to refactor our CA for JSP because WTP
works fine now and we almost don't use our one.
But we use our CA for facelets pages. And we can not use WTP's approach
for that case. Facelets don't use TLDs and tag libs xmls don't contain any
information about attributes.
Let's plan some time for this work for future versions.
