Does fingerprintAssetMap have to be true for inline?

Hi,

Currently the README makes it look like having `fingerprintAssetMap` set to `true` is required to have the add-on work. However, as I read through the code, if we have `inline` mode on, do we really need to fingerprint the asset map? In `inline` mode, the asset map file is read from the directory that contains all the built files so its content should always be up-to-date and we don't have to worry about loading an obsolete file that is stored in some cache?
