I think, having only one solver (as in MetaPost) is not that
problematic. OTOH, yes, you may make use of several solvers. But then
I think we should do the bookkeeping, whether a variable is already
defined (currently by the is_set() method), local within each solver.
Could be usefull ... I'm not sure.

AFAIRC in MetaPost there is a possibility to "redefine" the value of a
variable and "resolve" the equations. Might be a task for several
solvers. This would be much more elegant IMHO (compared to the
MetaPost way; MetaPost doesn't have (several) solver instances.)
