The short answer is yes.
Recently Microsoft announced that they will completely remove support of code-based sandbox solutions from SharePoint Online. We received multiple questions about future of Workflow Actions Pack. According to this announce, declarative solutions will remain working. This is a quote from Office Dev Center:
“Note that currently, we do not plan to deprecate or remove support for declarative (no-code) sandboxed solutions.”
Wsp package of Workflow Actions Pack doesn’t contain any code, it is a declarative sandbox solution. So, there is nothing to worry about. Actually, code-based sandbox solutions are not working normally since Office 365 launch. So, nothing changes for you even after removing of code-based solutions support.
