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.
Yes, you are right.
Whether the same is true for Hindi, I have no idea.
