Comment:

 {{{$pagenow}}} not being available at mu-plugin inclusion has an
 additional consequence, which has not been mentioned yet.

 {{{function determine_locale()}}} is checking for
 {{{$GLOBALS['pagenow']}}} in line 141. As a result, a network activated
 plugin, which is using one of the WP l10n functions during startup will
 cause a {{{PHP Notice undefined index…}}} notice on the login popup
 window.

 From a network administrator's point of view, I would not expect a big
 difference between a network-wide activated plugin and a plugin that I
 activated on every site in the network individually. (unless the plugin
 provides some network-specific funtionality)

 Plugin authors (or at least a considerable majority of them), might expect
 the wp core to reliably provide an identical environment, in both cases
 network activation and single-site activation.
