I would have nothing against it. This certainly helps with clear communications ("Put the longer lead in the square hole") and might also help to keep silk screens clean.

It would be interesting how the different pad could affect assembly. I haven't had many boards with rectangular pin 1 pads but with the ones I had, I found the rectangular pad a bit awkward to solder sometimes. But maybe it's just my soldering ;)

I had it on multiple PCBs with varying qualities. I never really had any problem with it. If we want to make it nice we could round the corners of the rectangle/square a tiny bit to make avoid solder not reaching the corners.

Just did a board with rectangular pin 1 pads the other day (after ages just with round pads) and you're right, it isn't an issue (at least for manual soldering). I may have had some false memories there.
The only drawback for rectangular pads I can think of is that they always occupy a bit more space than an equivalent circular pad which may be inconvenient for the layout.
Apart from that, it's a question of style.

It definitely is. I personally prefer all pads looking the same. Anyhow, there's nothing wrong with alternate packages having square pin as long as the primary package has all pads identical.
