Let's put this into perspective.
It's a line that has just come out of a huge financial problems from the last couple of years, only to be met with this landslip. The visit of Flying Scotsman has definitely been noticed by the press and through discussions from sites like this it has brought publicity to the Severn valley about the full line being re-opened post landslip and a draw factor to bring in a fresh audience that have heard of Scotsman but haven't had the time to go and meet the locomotive before hand.
In other words, from a publicity standpoint for the Severn valley (outsiders perspective) it looks to be very successful in that regard.
I know there are those who have questioned the choice of Scotsman. But we are what 65 years deep into Standard gauge preservation of the first heritage railways, almost as much time as the era that most of us enthusiasts primarily focus on regarding steam (1900-1968). At this point Scotsman reopening the line has become part of the lines history, and a small footnote in Scotsman's story spanning over a century now.
Heritage railways are almost like model or garden railways philosophies at this point 'as long as its safe for operation, they can run what they want, its their line'.
This is, unfortunately, the problem; however, as this debate has been going on for a few years, more or less at this point, we all know that a mine can't be financially sustainable/profitable in the UK for the minimal amount of coal that the heritage railway/traction engine community uses in comparison to steel or (formerly) the energy sector.

I think that, in addition to leaving those who are trialling oil firing to their own devices and seeing what the outcome will be like, the next best thing the sector could do would be to simply report some of the findings of biocoal trials and make the data/reports open access to the enthusiast community, maybe along with institutions such as the NRM putting out feature articles on their site such as when times steam locomotives ran on alternative fuels.
The current trials feel more like a scattered jigsaw puzzle of hearing loose stories of 'x line tried this coal type' etc etc, then utter radio silence for months with no publicised trials. More announcements in Rail Advent, as well as published results with data and anecdotes from loco crews, would be much appreciated.
This is kind of the problem with it being the sole surviving 'A1/A3' loco. It would be interesting as a thought experiment, to consider how popular another survivor or two from the class would be.
Would it be another loco in Hoskings' fleet? A society owned one like the Princess classes or Sir Nigel Greseley? Would it have a cosy preservation life somewhere, like on the NYMR?
If it was Papyrus that was preserved and saved in the NRM, would it be considered for overhaul again or left as a static exhibit piece like Mallard?
Certainly raises many interesting questions as a what-if exercise.
