It would be a shame that because of lack of time and resources, the project would not move forward faster and stronger. The more Ryan and team focus time and efforts on PW, the better for everyone.
Don't worry about lack of time or resources - I personally use ProcessWire on all my client projects, so it's something I've been working on steadily for many years and will continue to. My business depends on it!
Sometimes I get blocks of time where I can focus on it a lot, and other times I have to focus more on my client projects, but PW always moves forward because I use it almost all day every day. Though something I'd like to be able to do is less client work and more ProcessWire work. One thought that crossed my mind is to maintain another version called ProcessWire Pro (or something like that) that would basically be the same but include faster support by e-mail and several of my modules that I use in commercial projects. It might also include a separate support board geared for your clients, so they would also have a support resource should they ever need/want it. I was thinking something like this might appeal to the EE crowd that is looking for the guaranteed support and services beyond the typical open source project. The audience here would be the web designer/developer that does this for a living and wants something extra that they can't currently get from PW or other open source projects. But that in turn would help to open up more time for the project as a whole. Not everyone needs or wants this, but it might be nice to offer it for those that do.
