I strongly support a higher minimum blob base fees; this will be even more important if we decide to increase the blob target to 4 without increasing the max, as is currently under consideration.
One thing to note is that during the LayerZero spike, Base witnessed significant difficulties landing blob transactions, even with fees set well above what should have been required. We tracked it down to the way geth was handling blob transactions in its transaction pool. We submitted a fix which has been included in the latest release (1.14.9), which is perhaps not rolled out that widely yet. We also observed that FlashBots was not including any blobs in their blocks (also since fixed), though this was probably not a huge factor overall (<5% of blocks IIRC).
I expect the next spike in DA demand should be handled more gracefully. Still, a higher minimum fee would only provide added protection and in my view should be part of PectraA regardless of where we settle on the blob target.
