indent-tabs-mode is the mode variable, so setting it to t is not a
mistake.

You could do it either way.  Also, some modes don't have such a
variable, so only the latter way will work.

But why do you think we should only advertise one method, but not the
other?  There's no magic here, just legitimate use of public
documented variables: 'mode' is a variable and so is 'indent-tabs-mode'.

So I think I don't get your motivation for the report and for the
patch you provided.

Thanks.
