Equation domain and learning assessments

Hello all, With the realization that we aren’t going to fuss with the learning topic types, I still would like to ask this question as I do actually have new clients using this domain – in fact as soon as we shut down that work and the subcommittee, I gained three new clients who wanted to use it.
Anyway, I discovered today that the equation-domain and mathml is not included in any learning content, which causes problems for two of my clients who want to build math tests.
We can obviously add it as a specialization, but I wondered if this was an oversight?
It seems as though it should at least be allowed in lcAsset2 if not lcQuestion2.
I think the plan was to make the learningDomain compatible with 2.0 but not enhance.
I wondered if this is an oversight if adding the domain could be part of that effort?
