I’d be interested to know how engravers who use this notation decide when to use it. It’s very much a non-default option for me.
I’m in favour of Dorico allowing it (which it does, of course) but my usage of it is always exceptional: there would need to be a strong contextual reason to avoid [minim tied to dotted crotchet] in favour of [dotted minim tied to quaver].
It would also be interesting to know how such an implementation would work as an option in Dorico. Are there engravers who would prefer it as the default tie group in 4/4? I suspect not.
If Dorico were to allow this notation to appear only in appropriate contexts: eg on a piano stave where the other voice(s) have the rhythm [dotted minim - crotchet], that might be useful, but it’s a complex algorithm to write, devil in the detail etc.
