It is not about letting or not letting them. I would have to implement
it. (I am ok with it, but I am not going to prioritize my time for
nice-to-haves; though I would not mind patches submitted by interested
users).

I meant:

1. not reasonable in a sense that it has downsides compared to what we
   do now - save latex previews on disk
2. impossible in a sense that we do not have an existing toggle to store
   cached previews in memory. Such functionality would have to be added;
   and it is not necessarily trivial to add it.
