Not really. You know the old phrase "If It Ain't Broke, Don't Fix It?" The same thing applies here.
Sponge bob either needs to get cancelled or make episodes on a regular basis but Nick has to decide.
You see For Season 3 Nickeloden Held Back on showing Spongebob episodes because Stephen and others of the original SB crew had left the show and it didn't look like it would get picked up for a 4th season. So while Nick tried to get them to at least to agree for more seasons to be made, they aired the remaining episodes at a super delayed rate so no one would notice the show seemed "cancelled". Eventually they relented (though Stephen still isn't dirctly involved with the show anymore and some of the other SB animation/writing team like C.H Greenblatt and Aaron Springer moved on to other projects) and Spongebob got at least 2 more seasons. However the delayed policy worked really well as Spongebob still got megahit ratings, and Nick realized they could draw out the series as long as possible, airing episodes at specific times and getting really high ratings for them, espically the specials. (You may of hated how "Lost in Time" was promoted but that got 8.6 Million Viewers for a reason you know). It's not even that the crew aren't making new episodes at a slower pace then usual: Nickelodeon's just airing them that way to keep Spongebob on the air as long as possible. You can't fault the show because the executives find that the "show episodes at specific intervals" policy really works.
Man now I"m up to 7,000+ posts. Hard to believe it took me 8 something years to get that many. How long will it take me to get another thousand? Guess you're going to have to keep reading what I have to say to find out.... I hope you've been doing that anyway as I feed off the attention.
