Re: [ilreq] When does the ABNF work for Tamil consonant clusters?

Let me try to make my question clearer.  It is only about situations where the pulli is visible.

Given a word such as யாவற்றையும் (yāvaṟṟaiyum), should the break points for text segmentation, line breaking , drop letter (if the conjunct appeared at the start of the text), letter spacing in horizontal text, and vertical text representation conform to this?

or this?

The latter is what the ilreq document currently suggests.

A similar question arises when fonts don't produce certain conjuncts, for one reason or another, or where a ZWNJ is added to prevent a conjunct forming. Where are the break points for the following?  Are they:

Given that for a more typical rendering of the text the break points, as described in the ilreq doc, would be:
