To take it one step further, mathematical ideas which do not nicely fit within one of the highly developed theories then feels underbaked and less attractive to other mathematicians.
Knuth thinking about algorithms led to all these research questions about combinatorics, that have turned out to be very interesting, but are much more messy and disjointed results.
