Why is renaissance music generally ignored in "mainstream"* classical music

Pretty much title. After finding the keyboard works of Orlando Gibbons I've become absolutely addicted to them and renaissance music as a whole. Maybe it's just a peculiar taste of mine but I think that most people could get the same enjoyment out of the stuff that they do from similar style pieces by baroque composers like Bach and Handel.

*By mainstream I mean I've never seen it on any concert programs or as part of the syllabuses for any instrument in rcm/abrsm
