If the total number of active wanderers about the same just a more even distribution of types after the changes. Then not really a big deal, as you would always be ensured one with the skills you looking for. If it became more cumbersome for you because of a mod you are using? That is on you though. If you fire a companion they end up "lost" and gone from the game. Lost and dead two different things. If you check with the encyclopedia it say they "disappeared", meanwhile a dead character would look like; died in battle, of old age, natural causes etc, Look at it like people that couldn't find work and went elsewhwere, retired etc.
