Looking at the flag colours I cannot but think that Sweden is paving the way for Ukraine's membership.
I know Ukraine will not and cannot do this, but writing off it's East and Crimea would enable NATO membership and EU ascension.
No, it wouldn't.
NATO deciding it was willing to piss off Russia (which is why, without those active conflicts, Ukraine and Georgia were denied MAPs in 2008) would allow NATO membership. There's no actual rule that would prevent Ukraine from joining during the invasion (and even if there was, any NATO rule can be changed, either in a general way or to add a sui generis exception, by the same group -- all NATO members agreeing together -- required to admit a new member under the existing rule, so the rule would not actually be an additional barrier.)
"But," you might object, "even if there is not a rule preventing it, Ukraine joining while the Russian invasion continues would be impractical because it would immediately trigger Article 5, as long as Russian forces were engaging Ukrainian forces anywhere in the country, or even occupying any part of the country."
That could be managed, though, by admitting Ukraine while adopting either a general (for later review) or temporary with explicit time limits or other terminating conditions exclusion of some parts of its territory from Article 5 (not all the territory of all NATO members is covered by Article 5 now.)
