I understand your question. We just don’t create a bundle for linux-current-dev. There are several costs associated with doing so, and we decided it wasn’t appropriate for this particular kernel package.
We do specifically provide source code for everything, though, even if not through a bundle.
The kernel development document I mentioned in my first response includes the link that will get you to whatever version is current: Source RPMs (SRPMS)
But here’s a permalink to the source package for the linux-current kernel version as of this writing: https://cdn.download.clearlinux.org/releases/37360/clear/source/SRPMS/linux-current-6.0.0.rc7-52.src.rpm
