Absolutely, but it's an extra step that to me brings little practical benefit, since FLAC is already the source format & is more widely used practically everywhere outside Apple's ecosystem.
> Your format of choice should be dictated by your mobile platform - if you use iOS device or simply like iTunes, go for ALAC. Any decent player will handle FLAC and ALAC, but Apple requires ALAC. If Apple isn‘t a concern for you, there‘s no reason to use anything but FLAC.
I use iOS as my smartphone platform for now, (waiting for the Librem 5), but Linux on the desktop, so that's why I prefer FLAC. It's worth noting however that iOS itself does support FLACs perfectly well, just iTunes doesn't, (I prefer not to deal with iTunes at all, so not a concern for me), but if you use something like Airsonic, you're set.
I do have a set of AirPlay speakers however, since I wanted something wireless, but still lossless, which kind of means AirPlay is the only option & that does transcode my FLACs to ALAC on the fly, so there's definitely an area where I use ALAC, even if indirectly.
