For unsubscribe - yes.
Everything else - no.
But if I am using standards and they have an ad blocker that blocks some of the functioning of my site, am I also required to test my site against that?

I'd include _everything_ important in the "yes" category. If I cannot access the customer panel to update settings or notify them of a bug that is affecting me because I'm using Firefox ("works for 95% of users"), they're just not keeping up their end of the contract.
Remember, 95% excludes everything but chromium/webkit-engines.
Every company decides which customers are worth going after.
Might still be a business decision, but it's like saying "we'll drop any emails that indicate a mail client other than apple mail/gmail/outlook".
It's not surprising that the strongest protections always happen on the unsubscribe links, but not on the subscribe-links. That just needs to be fined out of existence, just like "you can order with one click, but you need 50 clicks and a three-hour-conversation to cancel".
Just like other cases, I won’t accept that it’s “just lazy” on the part of big tech companies. They clearly know how to adjust their internal view/reputation of a domain once it starts being used for “misbehaviour” and spam such that they start blocking it.
Thus they could clearly start by not doing so-and, maybe, they’re “really touchy” about domains with no initial “internal score” such that if a new domain pops up and starts spamming people they catch it fast. Its not necessary to break open Internet protocols, though, unless they want the breakage.
