And yes there is very much of the Torah shebaal peh Takanah that we still observe today in spite of the Eis Laasos that is why gemaras are to this day still printed without nekudos, it is said that is why the Gra wrote mostly abbreviations and more.
And the “takanah” to allow accepting a stipend also still exists.
That’s assuming we pasken like the Rambam, and that the Rambam wouldn’t allow a Kollel stipend. However, the poskim don’t assume that; they add the part about eis la’asos as an extra snif.
