That's true, talking about emerging trends or projects, that is common with altcoins, Bitcoin is strictly focused on building more on what has already been laid foundation on, their could be some newly introduced development under Bitcoin improvement proposals and you can get full details of them here on the technical boards or at GitHub, but when referring to projects, ordinals is not regarded as such to me because it's not under Bitcoin protocols but the network included it due to available block space and it's something entirely different from Bitcoin itself, altcoins have much of these developments and newly introduced projects, you can often visit the altcoins section to get more details.
