I thought about that and I still like "basic" more. There are other
words with similar meaning but I would like you to consider the
hierarchy of these concepts. I will repeat some familiar things to help
other people follow the reasoning.

These new patterns implement just basic Finnish hyphenation rules which
we learn in elementary/primary/comprehensive/basic schools. The rules
won't change and don't have special meaning inside Finnish context
(universally they do, of course, like "one-consonant principle").

The current (old) Finnish TeX hyphenation patterns are obviously based
on the same basic rules too. They add more rules or exceptions on top of
that in order to produce better typography and help with some compound
words. (This implements the "one-consonant principle" too but with
additions and exceptions.)

So there is hierarchy: there is the basic level without special meanings
and there can be higher levels with more specific goals. I came with the
idea of "hyphenation=basic" and "hyphenation=typographic" to show this
hierarchy but I'm pretty sure that there are other ways too.

Anyway, these are just names. There are manuals for explaining concepts
and meanings more clearly, like Polyglossia's "Language-specific options
and commands" section (polyglossia.pdf).

Thank you!
