Here's my answer: after several years going bootstrap-free and doing everything by hand, I realized I just ended up writing my own bootstrap equivalent, so now I just use Bootstrap or TailwindCSS. I don't use Bootstrap for the design or the components, I use it for the layout and utilities instead of building my own, and I code the design on top of it.
