ILR dependant to Citizenship holder dependant

Hi

I would be eligible for ILR in August 2023. Currently, my wife is on a skilled worker visa (exp May 2024).
so if she switches her visa to my dependant after I get ILR, will she have to apply again when I apply for Citizenship in the future?

Spouse of ILR holder and spouse of British citizen is exactly the same visa.

Note that her ILR clock resets to zero and a new 5 year route to ILR (2 x 2.5 year visas) if she switches to your dependent after you get ILR.
