    But most platforms these days have some form of CRC32 "acceleration". Adler32 is easy to compute so I'm even less concerned there.

    I spent a bunch of time optimising the code in [fpnge](https://github.com/veluca93/fpnge), which is [often notably faster than fpng](https://github.com/nigeltao/qoir/blob/5671f584dcf84ddb71e28d...), yet checksum time is basically negligible.

    Having said that, the double-checksum aspect of PNG does feel unnecessary.

    * AFAIK it does this while beating the original QOI in terms of speed AND efficiency
