I would have a use case for AVIF tiles in a pipeline for creating xyz
tiles from satellite imagery but it seems, as of now, gdal doesn't support
AVIF writing. Are there any plans to implement that?

AVIF -raster- (rwvs): AV1 Image File Format (*.avif)
which suggests to me that GDAL *does* support writing AVIF files.

Hmm. I am on Ubuntu 25.10. The gdal installed from the Ubuntu .deb
supports writing AVIF with the AVIF driver.
... but I have built 3.10.2 with GCC and with Clang and only the Clang
version has the AVIF driver. Something odd is going on.
I see the following in frmts/heif/heifdataset.cpp
// If the AVIF dedicated driver is not available, register an AVIF driver,
// called AVIF_HEIF, based on libheif, if it has AV1 decoding capabilities.
if (heif_have_decoder_for_format(heif_compression_AV1))
{
poDriver->SetMetadataItem("SUPPORTS_AVIF", "YES", "HEIF");
poDriver->SetMetadataItem("SUPPORTS_AV1", "YES", "HEIF");
}
if (heif_have_encoder_for_format(heif_compression_AV1))
{
poDriver->SetMetadataItem("SUPPORTS_AV1_WRITE", "YES", "HEIF");
}
so you have been doubly unlucky;
firstly the AVIF dedicated driver is not available and
secondly your HEIF library has readonly AVIF suport.
