Why OR another condition with true

[moste00]

I'm looking at the extensionEnabled(...) function, but some of its clauses are confusingly written as an OR between true and another condition. Ext_Zba for example

I can understand an always true or always false to indicate an extension that is always present, but what is the use with ORing another condition to true?

[jrtc27]

The true represents that there is currently no configuration for enabling/disabling the extension. The RHS of the or indicates that, even if you had not explicitly enabled Zba, B implies Zba.

[Timmmm]

Yeah, in the nearish future true will be replaced with config extensions.Zba or something like that. Sail's new config support isn't quite ready though - see rems-project/sail#865
