     misc/elscreen is documented as not functioning properply with
Emacs >= 24, so no you can't drop it, unless you have newer verified
information:

Declare that misc/elscreen does not support Emacs 24 or later

It uses some of obsolete variables/functions, resulting in an error on
Emacs 24 or later like this:

  string-to-number: Symbol's value as variable is void: last-command-char
