Any semantic meaning in identifiers means all your data is completely denormalized. 1NF specifically requires storing all data as irreducible columns[0]. Most 1NF violations aren't actually all that consequential beyond not being able to do useful JOINs on the data in the column, but doing it in a candidate key column is a bottomless pit of update hazards.

[0] This means no comma-separated lists in strings, JSON columns, serialized PHP objects, and so on.

Right: When making the tradeoff, consider how painful it would be if you ever have to rename. All the way to your users refusing to even pay attention to a change in identifiers they have cached. How complex a translation layer might you have to add? It might be very manageable. It might be just plain dangerous.
