Ways to make series finale work for the new episodes

There's an interesting theory/idea in the comments under an article about the new season on the fan site hypable. I don't know how to link to the comment, so here's the page to the article and I'll repost their post below [if the one who posted it there originally is reading this and you didn't want me to copy your post, message me and I'll remove it from my post]:

Basically, the poster says there's room in the timeline for them to fit in a new season or a few and theorizes how it could be explained -

You know, I just went back and watched the finale again and I actually think there's wiggle room in the timeline for a new season (or a couple). After Leo and Grace get back together, Will and Grace don't talk for almost two years. That's when Jack and Karen make up that scheme to get them together in the hospital room. Then they have an evening together in Will's apartment, agree to call each other and work out a time to get together again sometime and then Grace leaves. They both look sad and while talking to their respective husbands (presumably later that same night), they talk about how they always thought fate would keep them together but they feel like it might be the end, like there's been closure. Then it cuts to them meeting up again after their kids are grown up and at college, walking off together. Then the next scene is them on the phone talking about their kids getting married to each other and Will, Grace, Jack and Karen meet up at that bar and make toasts.

So, with all that said, I was thinking, it's possible that after they parted ways, promising to call each other and find a time to meet and then later talking to their husbands about their friendship being over, they could have said to themselves, "No, I can't have it end like this" and then both made an effort to reconnect despite their separate, busy lives. They could have had many years of newfound friendship together before having another goodbye, maybe a more natural one like one of them moving away or something like that. Then, the distance between them just grew from the literal distance they were from each other, causing them to lose touch as people do until they happen to meet up again while taking their kids to college. Then whoever moved away could have moved back - maybe because they didn't want to be apart from each other again, especially with their kids dating and then getting married - between that reunion and the night they go out to the bar (which is a long while after their reunion as their kids are now getting married).

The whole Jack being rich thing and Karen being poor and taken care of by him instead of the other way around wouldn't present any continuity issues, it would just be different and possibly an interesting dynamic we can look forward to.

There. I know I put way too much thought into this, but I guess I just need to have it all make sense in my mind for me to enjoy it fully when it comes out.
