Who is going to rebuild and host the current GDAL docker like this? Your question comes across as entitled — the answer is: whoever cares enough to either do the work or pay someone to do it. The source code is there, the release archives are staying, and it will be possible to build an old release in the future which can read & convert a file they find. Docker images provide a great *shortcut*, which means if you find a file you can trivially convert it *without* building GDAL. I'm sure eventually GDAL will produce multi-arch docker images, but that shouldn't be a prerequisite for this deprecation/removal. Debian 1.1 386 floppy disk images from 1996 are still available, and if you have a m68000, sparc, a s390 or something else long-gone you can easily find historic Linux release images with compilers which will happily run. x86 will not disappear quickly, today's Linux kernel releases continue to support 486s and they were discontinued over 13 years ago. GDALs source code is also held in the Arctic Code Vault and other archival libraries <https://archiveprogram.github.com/> — it's not going to disappear any time soon. Regards, Rob :)
