After a lot of protests over this, AICTE issued this clarification.

What continues to baffle me is the very existance of undergrad level specialized engineering courses for, say, agricultural equipment. From engineering POV, what specialized skill would be needed in these engineers that normal mechanical engineers or instrumentation engineers normally don’t get?

I guess it is okay, but only as long as there are prerequisites determining what courses you can then go on to do. What doesn’t make sense is them mandating bridge courses for students who haven’t studied what might be needed. Universities already do not have enough faculty to teach regular courses; would they have enough for these?
