The beach resort has been mapped with leisure=beach_resort before and after your change, that is not what i am inquiring about.  What i would like to know is why you removed the mapping of the loose gravel and stones at the shoreline.  That is commonly tagged with natural=beach - no matter if it is a natural occurrence or artificially created (just like natural=water is used both for natural and artificial lakes).

Please consider restoring the deleted mapping.  I am sure visitors of the beach appreciate information on the physical nature of the shore here.
