Meh. Don’t see the problem with Boost. Front is a simple endcap and re-dish – admittedly the re-dish is going to stop you swapping between Boost and non Boost, rear you need to space out the brake disc too. Very doable, not the end of a wheelset.
The most recent fork I bought was one of the clearance Yaris at Merlin, specifically because it was Boost as I need the extra space to get a bigger tyre in. Looking at that fork sale, it’s noticeable that the Boost-Yari is the first one to have sold out although it did take about a month to do so. Obviously a lot of folks are fine with the idea.
Hope are selling a front adaptor for pro2/Pro4 hubs now and considering one for rear as they’re getting s lot of questions about it. No reason to need Boost at the back just because you have s Boost fork, so right now if you have Hope or DT hubs, a Boost fork is simply going to need about £30 of alteration to your front wheel, or under a tenner if you do your own dishing.
