As-action?

In the version of allyourbase.jam I have there are rules defined for
Cc, C++, etc. that redirect to e.g. Cc-Action. However, there does not
appear to be a pair for As and As-Action - the rule for As is:

rule As
{
DEPENDS $(<) : $(>) ;
ASFLAGS on $(<) += $(ASFLAGS) $(SUBDIRASFLAGS) ;
}

This seems to be preventing me from creating a new As-Actions rule in
my tools-specific .jam file, in the sense that if I change this in
allyourbase.jam, I'm concerned I'll have to then fix all of the other
toolset files, or at least, all the ones we use. 

It might be as simple as redefining AS, but even so, what is the
reasoning behind this? Or is it just historical, that is, no one has
yet bothered/needed to implement As-Action?
