Anyone else feel like we don’t have enough fugues in F major?

In the last of Bach’s four layerings to the fair copy of The Well-Tempered Clavier, we see some beautiful details that would have been lost had Bach not made this last series of revisions in the 1740s. It makes you wonder if Bach would have made even more, should he have lived as long as Telemann!

Bar 42 reads like this in A1-A3 into the 1740s:

Then, in A4, Bach found expression in the tie and 32nd notes:

Such a revision physically looks like this on fair copy:

This particular revision may not be immediately clear to the naked eye, but some are (see the e minor revisions at the bottom of the post.) I believe it was X-ray technology that led to such breakthroughs in the scholarship, but some layers might be a sort of ‘white-out’ or paste that physically would stand out on the paper— any expertise would be appreciated in the comments! We know that in the Saint Matthew Passion, Bach quite literally ‘layered’ smaller pieces of paper onto the manuscript, but I think that has to do with repair, not necessarily revision. One famous layering in A4 looks as if it’s been pasted onto the manuscript… but it could be my imagination. From the first fugue, BWV 846:

WTF Bach is free to all! Let’s spread the awareness of contrapuntal mastery. However, if you support financially, you’re much less likely to write parallel 5ths.

There are a number of revisions also in the F Major prelude. Interestingly, the length of both prelude and fugue remains unchanged between earliest versions and the fair copy. Bach had the general harmonic rhythm right, but smooths out the insides of some measures:

(Early versions, followed by the fair copy)

And so on… (more demonstrations in the episode.)

I finish the episode with four beautiful revisions to the e minor prelude (covered in Ep. 114) again made in A4. These are typical of his final revisions to the WTC1, bursting with 32nds. Here, one can somewhat plainly see the difference between inks:

Before these revisions, the melody was as follows:
