So you are saying that indent-to should take care of not inheriting
text properties from preceding text?  Or are there any other problems?

As for tabs, the width is controlled by tab-width, but indent-to
already takes that into consideration.  Am I missing something?  (If
you are thinking about tab-stop-list, that is only used by commands
that move or indent to tab stops, AFAIK.)
