Yes, and I have argued in http://www.dkuug.dk/jtc1/sc2/wg2/docs/n2141.pdf
that it is illogical that Devanagari has a mechanism for forcing conjuncts
and European scripts do not, but it is instead left up to individual type
designers to figure out and build into their fonts with complex kludges in
OpenType and ATSUI. Not that these technologies aren't powerful and
wonderful and good for fonts -- but they are not robust and reliable and
flexibly user-overrideable with regard to end-user choice.

Currently, we have (as for Devanagari) a prohibition on addition of
ligatures. But we have no mechanism for producing them, and it is
wrongheaded to claim that it's a feature of Devanagari worthy of plain text
but not so for Latin.
