Improved Bookerly

Is this only for the occasional page, and the next page has a new paragraph at the top of it? If so, this is widow/orphan handling kicking in, eliminating a widow (a single lone line) on the bottom of the page. It just happens to be happening at the start of that chapter with this particular font. (If it's consistent from that point onwards, i.e. the bottom margin has really changed, this sounds like a bug.)

You should not talk about pirating Bookerly. It's against the rules.

As for the problem with Kobo and Bookerly, that problem is not a problem when reading ePub. Why would you read KePub when KePub is very buggy?

The Bold variant was already set to a Panose weight of Bold. I don't think it makes any difference on a Kindle but on a Kobo ereader, it helps with kepubs showing the correct font variant.

But the fonts work as is with ePub because RMSDK has superior font handling compared to the disaster that is Access (KePub renderer).

If I increase the boldness on DaltonMaag in the middle of a chapter, the bottom margin doesn't change. However, when I move to a new chapter, the bottom margin is consistently higher after this. In other words, as you suggest, it looks like a bug

On Panose information, I saw and tested myself two approaches: (a) strip the Panose information altogether via ReadifyFont; (b) edit the Panose information via FontForge to meet the Book/Bold rule. Is there a difference? I verified with Kobo books aquired from the Kobo store (kepubs) and with KOReader and in both cases I could not see a difference.

Try the following...

Load the ePub into the Calibre editor. In the CSS, remove any instances of windows nd orphans. In the body class (if such does not exist add one) and you want to add in widows and orphans with a value of 1.
[quote]body {
widows: 1;
orphans: 1;
}[/code]

This is what I use for body....

body {
  widows: 1;
  orphans: 1;
  margin-top: 0;
  margin-bottom: 0;
  margin-left: 0;
  margin-right: 0;
  text-align: justify;
}

This may solve the problem you are having.
