for apt feature requests/proposals? Yes.

How does your ISP track "file sizes"? Does it really count how many bytes are
transferred over every individual TCP connection and will start throttling each
TCP connection after 100 kB?

I never heard of one. I'm from Europe. Can you name examples?

What has "displaying the total sum of mega bytes" to do with the problem?

What does the order in which downloads are done to do with your ISP throttling
them? You say your ISP throttles "downloads" of bigger than 100kB. But what you
say now also means that it puts each "download" within the context of the
"downloads" that happened before and after it. So what *exactly* is your ISP
throttling policy?

Currently, out of 44539 packages, there seem to be 24849 that are smaller than
100kB.

Did you consider using a local apt proxy or cacher?
