Maybe load this data only when needed and erase them always afterwards.

What is the problem with erasing the data? It is just a simple loop
erasing it all, or?

Aren't these data only needed in custom operations? Then just
loading/unloading them seems not be operations that will be very
frequent. They are not more frequent than commands if flag them and
erase them at command level. And a 0.1 seconds delay for certain
commands that either load libraries or are meant as information
commands is not very much.
