为什么 PPP 优先使用字节填充？

我读到 PPP 可以使用位填充和字节填充，但我想不出任何理由来说明为什么字节填充更受青睐。你能吗？

从一些教科书中抄袭而来

PPP was clearly designed to be implemented in software, not in hardware as
HDLC nearly always is. With a software implementation, working entirely
with bytes is much simpler than working with individual bits. In addition,
PPP was designed to be used with modems, and modems accept and transmit
data in units of 1 byte, not 1 bit.
