I feel like all agencies should stay away from JavaScript frameworks unless they are willing to be open with their clients on how much time will go into maintaining the project. My agency regularly take over older JavaScript projects - built in whatever JS-stack was trending at the moment. There are always big parts of the stack that are no longer available or in active development. Not to mention the enormous hassle it is to bring dependencies up to date for a JS-project that hasn't been updated in three years. Depending on the circumstances we usually recommend moving it to a boring CMS like WordPress unless there are compelling reasons to double down on the JavaScript stack (if it really is more of a web application for example.)
