Checking my mail archive, the HTML part of multipart messages is on average 5 to 10 times larger than the plaintext part. Such a factor is essentially never irrelevant, even with decently fast connections it often takes me a minute or so to download a day’s worth of e.g. debian-user messages.
Similarly, I’d be quite annoyed if my local IMAP cache took five to ten times as much space than it does at the moment for no reason whatsoever (other than filling up an extra 8 to 18 GB).
