Don't know how I missed this the other day! Sorry for the late response.
Most likely not. Assuming the wait times for updates and testing remains as it currently is, it will only take a few days to be released. When a mod initially gets released to Modhub, I have been updating the download here to direct to the giants site for download. Adding early access would require removing the link to the "old" version to add the direct download for the update only to re-add the link to MH in a few days plus managing multiple file distributions. I have also personally seen weird issues with the MH "updates available" getting confused with manually downloaded versions up updates are added to the mod folder.
TL:DR - it is a bit of work for only a couple days early access 😆. If testing times change I will reevaluate for sure.
