The next-gen PHP images already includes basically all the usual extensions, however they are missing the widely used "intl" extension. While it's easy to install additional extensions (and we're currently doing that), we're losing a lot of time to it (the installation of the intl extension takes roughly 2 minutes on average, and it's the only other thing we have to install on top of the cimg images). The intl extension is required by a lot of widely used libraries (phpbench, among others), so it would be great if you could bundle it with the images going forward.
