Status of AVIF support in Fedora

Greetings everyone, TL;DR Will there be AVIF (AV1) support for applications using libheif in Fedora? A while ago I stumbled upon AVIF files not being supported by applications (gThumb, ImageMagick, GIMP) in Fedora [1]. It appears that the applications mentioned have switched to libheif for AVIF support in favor of libavif. Since libheif also provides/requires patent encumbered libraries/codecs (libde265) related to HEIF it is provided by RPMFusion. AVIF, however, is not encumbered by patents as I understand it [2]. So it seems we need a compatibility libheif-av1 or the like to allow applications provided by fedora repos to enable AVIF (AV1) support using libheif [3]. I found two threads ([4],[5]) in the archives regarding HEIF and AVIF. But none of them are conclusive with regards to enabling AVIF support. Are there any plans to enable AVIF support in applications that use libheif as their provider? If so, where can I find information regarding the status? I apologize in advance if any of the above is not entirely correct (or entirely incorrect). Aim of my message is to better understand why support for AVIF is lacking in some applications and if that can be fixed.
