I'm relatively sure we're only left with those two data points of Hogan singles matches being on the same card as a WWF Title match (in his prime run, that is), so one instance of it out of two occurrences is pretty meaningless since we have almost no sample size at all.
But as far as WM VIII goes, it makes sense that it turned out that way. They weren't going to have Hogan lose his retirement match, so they couldn't have him involved with the title, and there we were.
There's no way in hell Hogan goes with this, but if they wanted to create a big star they always could have kept Sid as a face and had Sid win a midcard "retirement" match against Hogan (then ala Hogan/Warrior they embrace and Hogan gets the big sendoff) while concluding the show with Savage beating Flair for the title.
