That's indeed some significant size increase. I'll need to investigate why and what's going on there. I tried to switch to rollup sometime ago, which would help the tree shaking part, but it still suffered some major issues for me.
Just opened bundlephobia, glamor-jss scores at https://bundlephobia.com/result?p=glamor-jss@1.4.1 20.3KB while
JSS https://bundlephobia.com/result?p=jss@9.8.7 scores 6.9KB and the preset https://bundlephobia.com/result?p=jss-preset-default@4.5.0 5.3 KB
JSS + preset = 12 KB
I think glamor-jss has high potential to become smaller if relevant parts are reduced. Also it might be smaller if tree shaking is applied, but that would require all dependencies in esm.
