Isn't it a tiny amount of data storage anyway? And if the Bitcoin devs really see a potential problem/exploits with it down the road, I'm assuming that in a future release it can be either be reduced or eliminated?
With Omni (what Tether uses/used) and Counterparty (what Rare Pepes use) the data storage is relatively tiny as just a few bytes of non-standard data are being added to a regular tx. The difference with Ordinals is up to an entire block can be consumed by one data file, so the theoretical limit is close to 4 MB. However, whoever is sending the tx would have to pay an enormous fee for it to get picked up by miners.
Because Ordinals txs use Segwit and Taproot, a lot of this extra data can be pruned by nodes so it doesn't necessarily get added to the blockchain permanently. However, there could be some changes made to Core in a future release if this thing really takes off and it becomes a "problem" in terms of blockchain bloat.
Will be interesting to see how it plays out.
