No build progress when running microbundle command

currently when running microbundle command, there is no indication as to what is happening and the progress of the process. The console just stays empty for 2-5 minutes and spits out the bundled output with sizes.

I have been through the configurations/options but found no option which enables showing build progress.

Any plans for adding this feature?

The issue names no files, tests, or entry points. Start by locating the microbundle command implementation and its existing console output, then verify that a visible progress indication appears during the 2–5 minute build before the bundled output is produced.
