Indeed: that is the thinking.

In contrast to the situation with \newXeTeXintercharclass, there is not
currently anything in the .ini files for the LuaTeX-specific allocators.
We therefore felt it was too much to do in one release to address this
as there needs to be some discussion first and very likely careful
timing with the LuaTeX package-development community. We are very
mindful of the current 'luatexbase'/'luatex' situation, hence wanting to
be sure we get agreement on the required approaches.

At the moment the focus needs to be on the current update. Once that is
settled and shipped to CTAN I'll start a new thread here asking for
thoughts on the LuaTeX allocator situation. Probably a lot of the code
is essentially written already, so what will be important is an idea of
what is needed in the format.
