I hope I'm submitting this feature request to the correct place, not quite
sure.

Accessing the files attribute of an input element returns the files as FileList
object, which is - AFAIK - part of the FileSystem API and therefore grants only
read-only access to its contents.

Unfortunately there are several common use cases which would require the
ability to programmatically _remove_ particular files from the FileList, which
seems not to be possible currently.

For example:

a) Checking the file.size for some limit before uploading, if limit is exceeded
exclude the particular file from uploading.

b) Giving the end-user an opportunity of reviewing his file selection and to
exclude accidentally selected files.

Here's the discussion of a guy facing the same problem:
