Unless you used dead front GFCIs.
If you provide GFI protection for the small appliance branch circuits with a GFCI receptacle at the panel you would have a violation.
It's all in the details.
Why anyone would do this is unknown to me.
It is a solution if you wanted GFI protection from a fuse or obsolete CB panel.
Why not use a GFCI receptacle at the point of use?
Have you tried to install a GFCI receptacle in an old box?
