Not to mention that all providers of Mobile Bank ID (which, as you mentioned, is by far the most widely supported one) are private companies, mostly banks, which have no duty to take you on as a customer.

If you for whatever reason can't or won't get an account with a Swedish bank, you're effectively cut out from large parts of online services.

I really think the government needs to realize they should provide ID issuance digitally to ensure that no one is left out.
