Unless you totally don't like a particular track, or you need a totally new track of something you do not already have recorded...
...you don't necessarily need to "re-record" just to fix a few notes or a few hits or a few chords or a few phrases.
With cross-fade editing, I've extended chords/notes MANY times in the DAW...and I guarantee that you could not find the edit point with your ears!

Especially things like synth pads, organs, strings...they are very easy to manipulate in the DAW.
I would say that at least 90% of the time, you already have all you need within your existing audio tracks...you just have to do some creative editing by taking from one section, manipulating as needed, and then adding it at the required section.
I’m sure you done some of that type of editing, haven’t you…?
I've always said...to me, the real strong point of a DAW, are the editing capabilities.
Except for creating some basic scratch tracks during pre-production, just to lay out the song structure and it’s tempo....I've been recording "MIDI-free", audio-only sessions for quite awhile now.
It's just a question of knowing what you can and can't do in your DAW.
And…I will often record some additional “sounds” when tracking.
Like…long chord strums…or additional cymbal hits…or certain vowels and phrases…
…that way, when I am editing, I can also use these if needed to edit into the existing tracks.
It’s just a question of knowing ahead of time what it is you want to do with a song.
If you just record a bunch of tracks…and then wait until the editing/mixing phase to consider arrangements and song direction…then you are really still doing pre-production…which is fine, but that’s a different use of studio time.
With a good DAW and it’s editing capabilities…most needs can be met without having to involve MIDI tracks as a “safety net”…
…though like I keep saying…if you prefer using MIDI tracks…there is nothing wrong with that, it’s just a different SOP.

I prefer not to.
And…let’s not now get into a whole extended debate about what can and can’t be done within a DAW…
