Core: Exclude callbacks & deferred modules in the slim build as well

mgol · web-flow · commit fbc44f52fe76 · 2020-01-20T18:58:23.000+01:00
So far, the slim build only excluded ajax & effects modules. As many web apps right now rely on native Promises, often with a polyfill for legacy browsers, deferred & callbacks modules are not that useful for sites that already exclude ajax & effects modules. This decreases the gzipped minified size of the slim module by 1760 bytes, to 19706 bytes (below 20k!). Closes gh-4553
