Nah, I’ve been toying with writing a compiler and that’s where I’ve gotten to too, it seems to my inexperienced self at least, if what you’re implementing is a specified language, combining the phases makes sense since you only have one thing per language, but while making a language and experimenting, having them be separate helps reduce a lot of complexity in the parser for things like tokens that go across multiple lines.

I have no idea if the above observations are generally true, but that’s been my experience with the handful of parsers I’ve thrown away because they get too unwieldy for what I want.
