Probably early and likely will come via MDN, but keeping track 0:-)

Indeed available via MDN: https://caniuse.com/?search=masonry

Currently in two entries:

• https://caniuse.com/mdn-css_properties_masonry
• https://caniuse.com/mdn-css_properties_masonry-auto-flow

Indeed, this is covered by MDN data (via mdn/browser-compat-data#7249), but it appears there may be more work to be done.

grid-template-rows: masonry is covered here:
https://caniuse.com/mdn-css_properties_grid-template-rows_masonry

masonry-auto-flow (as mentioned above) is covered here:
https://caniuse.com/mdn-css_properties_masonry-auto-flow

But grid-template-columns: masonry is missing, and mdn/browser-compat-data#9078 suggests that it may actually be (incorrectly) covered by this entry:
https://caniuse.com/mdn-css_properties_masonry

Additionally, these do not come up when searching for "masonry":
https://caniuse.com/mdn-css_properties_justify-tracks
https://caniuse.com/mdn-css_properties_align-tracks
