Sure, but the thing I'm proposing
spectre_v2_task_isol=
describes it more precisely, IMHO. :)
I.e., "enable/disable spectre v2 task isolation".

Hmmm, crazy idea: can we extend the options of spectre_v2= nstead?
spectre_v2=user_isolation,... spectre_v2=kernel,... spectre_v2=task_isolation,...
and so on?
This way we can do a couple of option switches in one go.
Hmmm?
