hi romain, i've seen different (special) cases which would have been easier with such a spi - e.g. the integration of custom "module-binding"/qualifier/... concepts (without annotations) - not only but also - for injecting beans of other containers which don't force annotations (and e.g. @Named isn't useful)
most parts are possible via std. cdi-producers (that's quite verbose and in many cases hardly ~accepted in projects), std. cdi-extensions (to get the acceptance for it is sometimes also not that easy, because it can get quite ~complex) or the resource-injection spi (it also has its disadvantages, but it's easy/easier to use). most use-cases came up around migrations to ee6 -> the demand might decrease over time... some switched from a step-by-step migration to an immediate migration and some just migrated to something different (in the end topics like that can be a significant part of the decisive factor). -> large/r migration-projects might benefit from such an option (i still know large projects using ee <= v5). @OWB-1287: i'll have a look at it next week regards, gerhard Am Do., 9.
