The average tenure of a person in engineering role is so short that very few employers are thinking about developing individuals anymore.
The actual way this gets approached is "If you want seniors, you must hire seniors".
I'm not sure how this plays out now. But it's easy to imagine a scenario like the COBOL writers of the last generation.
It's a self inflicted wound. Companies do not reward loyalty. They do not give out raises congruent with what you can find if you leave. Business-types unirionically think seasonal layoffs is a "good thing." Self hemorrhaging your institutional knowledge is insanity
