+Refine generic typings using `extends X` when appropriate
+
+Typescript 4.7 has stricter requirements around generics
+which is explained well in the related PR:
+https://github.com/microsoft/TypeScript/pull/48366
+
+These changes resolve the errors that these packages will
+face when attempting to upgrade to TS 4.7 (still in beta
+at the time of writing this). Landing these changes now
+will allow other TS libraries which depend on these
+packages to experiment with TS 4.7 in the meantime.
