How stable is the "remove vehicle limits" cheat?

I have a major wooden coaster (my own design) with a sky-high excitement, and it's currently running 4 trains of 6 6-person cars. In an effort to draw more guests into the park (the objective) how wise would it be in terms of stability to increase the trains to 8 cars? It's not pushing the limits by much. Another similar question involves increasing the number of cars in a water coaster (it uses individual cars) to 15-16, which is 4-6 more than there's room for in the station (but it has a long stretch of water track at 4 mph into the station long enough to safely hold them). One default design has 13 cars in block mode, and I'm wondering about this ride from both a game stability and possible practical problems standpoint. Basically it comes down to whether the cheat is stable with a slight increase beyond normal limits.

Going beyond the original limits is usually very stable. There are some edge cases with unexpected behaviour (such as #11756, #12851 or #13746), so that's why it is still marked experimental.

I use that cheat regularly. I don't "appear" to have any problems. For example I have max station length of 32 tiles, and on an air-powered coaster I can have 92 cars before it's too long for the station. A lot of my designs have one train with the max amount of cars that will fit in the station. The only reason I don't do that with rides like the water ones, is purely that it "looks" wrong to me. 

Just as a note .... Don't do that with the transport rides, as if you have them go up an incline, you'll get speeds of 1kph or less.  Same for the log flume, splash boats, and river rapids.
