Has a better practice of build.minify with plug-legacy?

[zheung]

Since v2.6.1 default build.minify to esbuild(e4892be),
all configurations that do not set build.minify BUT use plugin-legacy will receive an Can't use esbuild as the minifier when targeting legacy browsers because esbuild minification is not legacy safe error.

The solution is simple. Just set build.minify to terser.
But is this a best practice? How about the default is esbuild and the legacy part uses terser?
I don't know the result because the current plugin-legacy doesn't support configuring the minifier separately.
I think the relevant documents and options can be better done, to guide users to use the best configuration with plugin-legacy
