SWOOLE_BASE vs SWOOLE_PROCESS - why should SWOOLE_BASE be preferred?

[linuxd3v]

The differences between these 2 modes (SWOOLE_BASE vs SWOOLE_PROCESS) are not very clear (at least to me).

When I look at the documentation - I was assuming (perhaps incorrectly) BASE = basic, so I would automatically configure SWOOLE_PROCESS mode thinking that is better and preferred.

But now - I see that swoole version 5 has made SWOOLE_BASE as default, and I also see some indications that SWOOLE_BASE should be preferred mode:

#4757
SWOOLE_BASE has never been deprecated, instead, it should be the preferred mode.
The reason why SWOOLE_PROCESS is still the default mode today is for backward compatibility.

Is there some documentation on why SWOOLE_BASE should be preferred and how is it better than SWOOLE_PROCESS?
