Major I tried to install JBT (Abridged + Additional JBoss Tools) to Eclipse JEE RC3 and I got Remediation Page with this error message:
Your original request has been modified.
"JavaScript Development Tools" is already installed, so an update will be performed instead.
Cannot complete the install because of a conflicting dependency.

JBDS can be installed without problems because BYOE doesn't include JavaScript Development Tools.
I see that Eclipse RC4 has been released but I can't find Eclipse JEE RC4 package, so I have tried to install JBT/JBDS into Eclipse SDK platform RC4. Both can be installed without problems but it seems that Eclipse SDK platform doesn't contains Eclipse Web Developer Tools so this test may be irrelevant.
