I read an article about changes Peter Jackson made in the movies that the article thought were improvements, one of which was changing the balrog in Moria from man-sized to enormous. I could not remember one way or the other, but I started searching on balrogs.
I came across comments from random fanatics who appear to know the stories behind the stories, and I was surprised that JRRT's views of balrogs changed drastically over time. Apparently originally there were at least many hundreds but the lesser balrogs might have been somewhat comparable to orcs in power [I cannot remember where I read that]. Over time, JRRT kept thinking they should be rarer and more powerful.
According to https://tolkiengateway.net/wiki/Balrogs the son said of the number of balrogs
In the margin my father wrote: 'There should not be supposed more than say 3 or at most 7 ever existed.'
The wiki says that predated the publication of The Silmarillion.
