Perhaps it is, but we have actual Russians who think it's a good idea.
I recall questioning that point some years ago, and Oleg replied that
they'd done that intentionally because (a) technical Russian uses a lot
of English words, and (b) it's easy to tell which is which thanks to
the disjoint letter sets.

Whether the same is true for Hindi, I have no idea.

Hmm.  I think all of those entries are ones that got added by me while
absorbing post-2007 Snowball updates, and I confess that I did not think
about this point.  Maybe these should be changed.
