Based on what I have read so far, Makehuman seems to have a number of different template meshes which are targeted to different characteristics such as age range/gender/etc and which are deformed as required under program control.
I wasn't looking to disable the age slider as such, but to only download those meshes used to create adult models. That way, the age slider could stay but Makehuman simply wouldn't work when trying to create a child model.
I'll have a bit more of a read.

This is largely a true interpretation, although I think you might be mixing targets and proxies a bit. There are no child "meshes" (in the way that there is a female-genitalia alternate topology), only modifiers of the default mesh.
Anyway (since child things are modifiers, and not proxies) there are two groups of modifications: macro modifiers and standalone targets. Technically, they look largely the same, but a macro modifier is an aggregate of a range of target files which are co-distributed with the makehuman source code (see
https://bitbucket.org/MakeHuman/makehum ... at=default for list). They are also referred to explicitly in the code, which makes MH crash if they're not there, unless a code modification is made.
The standalone targets are less integrated. They are downloaded separately from a different repository and are not as required (although removing one might cause glitches too).
The child-related things are macro modifiers hanging on the age slider, which makes them more difficult to remove than, say, the pointiness of the nose.
