Wouldn’t this be easier?
On a TV budget it would be much too time consuming (and therefore more expensive) to CGI everything like ROTS did. You could argue that the same applies to most movies also.
I’d imagine a Kenobi series would be much easier and cheaper than the two series currently in production. Plenty of desert in California, and places like Mos Eisley is hardly the craziest locations in the SW universe to build as sets.
