Enhancement request: Make as as many package options as possible settable post loading

[EvanAad]

Please make as as many package options as possible settable post loading. Some document classes, such as beamer, load babel, in which case the only way to pass babel package options is by including them in the class option list. This makes it unwieldy and ugly. Take layout, for instance. Is it necessary to pass it as a package option? Can it not be specified post loading? A mechanism similar to enumitem's \setlist or to tikz's \tikzset would be great. And then perhaps mutliple values can also be separated by commas, as is usual, rather than by dots.

babel is a huge package and there is no point in storing everything in memory just in case. If you want to add options to babel, use \PassOptionsToPackage{<options>}{babel} before loading it (eg, before \documentclass). Alternatively, \PassOptionsToPackage{base}{babel} makes babel to almost immediately exit in such a way a second \usepackage[<options>]{babel} is possible.
