Anecdotal: I agree because everywhere I have worked were backend-senior heavy -- they think frontend is easy and not worth touching, and they are the ones who makes decisions on "the next shiny things" for backend things. In my last job, databse migrations happened twice in just two years and we spent a total of one year of engineering time on it -- every single table, not just some non-critical ones. When things broke or when upper management was asking why thigns were so slow, they just blamed the front-end learning engineers for not being experienced enough.
