ᐅ New door frames over old door frames?

Does anyone have experience with door frames and doors?
I have steel door frames in my apartment that extend under the screed. Removing them proved to be only somewhat practical for two doors that needed to be replaced anyway.
The only issue for me is the appearance of the old steel frames; otherwise, they are basically fine.

I’ve read that there are also “clip-on” frames, which are purely cosmetic and cover the old steel frame to achieve a modern look.
On average, you can expect up to a 70mm (3 inches) loss in width and about a 35mm (1.4 inches) loss in height.
I can accept the loss in height, but 7cm (3 inches) in width is quite significant.

Has anyone installed these renovation frames before and can share their experience?
How do they hold up over time, is the loss in width worth it, and so on?

Jamb over jamb means a custom-sized door.
Even if the jamb is cheaper, the custom door likely won’t be.
The flexibility for door replacement, for example with a new door in case of damage, or a glass door, will probably only be possible through custom manufacturing.
