First, you omitted the OTF features we request for Tamil -- aren't
they needed for the Supplement block? if not, why not?

Next, we should consider what the main supported platforms do with
this block -- don't they come with other fonts configured for this
block? if they do, we should at least use 'append', not 'prepend'.

And finally, is the license of Noto Sans Tamil Supplement free enough
for us to include it in our sources?
