The most disturbing thing with these long links is that Teams lists have a "URL" type of column, and it cannot take a link to Teams, as it is restricted to max 256 character long URLs. So Teams cannot link to itself, because Teams links are longer than what Team consider links allowed to be. Changing that limit to more than 256 is urgently needed, and seems not a feature that should take years of testing, but rather a fix to a serious bug/design flaw.
