Why has the registrymodifications.xcu file grown so huge?

Mine is now more than 13MB large! It used to be a lot smaller.
I wonder if it’s an LO bug that it’s now so bloated.
What’s the size of your registrymodifications.xcu?

Info: Mine is
1.669.995 Bytes for LibO V5.2.0 installed under Win 10 and
1.138.071 Bytes for LibO V5.1.1 Portable…

Thanks. So, yours are less than 2MB. I believe mine somehow got filled with junk data…
