That's your interpretation.  The current interpretation is that SPC is
a variant of TAB which works similarly except that it stops completion
at a word boundary and adds a - or a SPC if that can enable completion.
This allows SPC to obey completion-styles.
Your interpretation basically implies that SPC can't obey
completion-styles.

To me the above tells me you don't want partial completion.  So turn
it off.  That's what completion-styles is for.  I changed the default
on purpose.
