That’s not fundamentally true about ISDN - in North America, at least, most basic rate connections and every single PRI I ever encountered had eight-bit-clean channels and were true 64kbps.
With modems (I assume you mean analog modems,) that was only part of the reason. There were others that would have been far more difficult to solve in practice, and there was largely no point in doiny so as xDSL technologies came around at roughly the same time.
Multilink PPP worked quite well, even beyond bonding two channels.
