We've been using GWT-RPC for a while now as well, and the alternatives seemed less desirable the last time I poked around at them. Reading over some of the cited poor choices GWT-RPC, they seem to me to be more like "features" and "trade-offs" instead of simply being bad choices.
Version skew is a good example. It's cited as a negative, but in other contexts is actually a positive. The client has outdated information regarding the service/model objects? It SHOULD blow up. Old/new clients/servers communicating with each other I'm sure is commonplace at Google and in it's related applications, however this is absolutely unheard of in a static deployment environment, such as in consumer or enterprise deployments. Version skew actually catches deployment errors during testing in those situations. The compile time argument has me scratching my head. I've listened to many presentations from Ray/Daniel regarding GWT (big fan, btw). The compiler is often cited as what separates GWT from those other JS lib technologies. I especially liked Daniel's dig at Angular via Singular, but it was a good demonstration of how powerful compile time analytics can trump a runtime library. To paraphrase: we have a powerful compiler, let it do work for you, you can't get that from <insert latest JS lib here>. To cite GWT-RPC as requiring the compiler time-hit that it does strikes me as a choice/trade-off, not a negative. For some applications, it may be a "good thing" (tm), but a "bad thing" (tm) in others (see version skew above). To me, this feels like GWT is a little self-conflicted. We have this compiler, it could do a lot of work for us, but we don't want it to do too much work for us because we want it to be lightning fast! Maybe I'm just old-fashioned, but I'm ok with compilers taking extra time if it serves some value/purpose. While I know there is this great "quest" to speed up GWT compiles such that developing in GWT has very little overhead as compared to just regular JS development, I would implore that a "carrot" approach is taken over the "stick." If, as a developer, I'm willing take a compile time hit for a feature (GWT-RPC or otherwise), seems like having the option would be a "good thing", while on the other hand the GWT compilation speed can still be lightning fast when we ask less of the compiler by not using such features.
