The standard way to handle compatibility is to define increasing compatibility
level and to default to the highest supported.

Something like:
GP 1.39 level 0
GP 2.1  level 1
GP 2.3  level 2

so that scripts can start with 
default(compat,N)
to specify the compat level they need.

Unfortunately the GP compat level is decreasing and we are 
already at 0...

Also 2.2 already have several incompatibilities anyway for which we do not
provide compatible alternatives, unfortunately.

Maybe new_galois_format can simply be a flag to polgalois() instead ?
