It was an issue when I had a to short TXDELAY, some had fast enough radios, others did not. Particularly, some squelch circuits can be too slow to act, and had to accomodate that, even when I prefer open squelch and software carrier detection. Unbearable when you also listen, but the best for the packet link using a KPC-2, KPC-3 or KAM. That's my personal experience, I still keep one KPC-2 and one KPC-3 in working conditions.
