This change doesn't do anything to prevent in this case Tibetan from "accommodating recent changes". It makes it possible to support the language as it was used historically and as I understand it is used presently. Even if it were to change presently, there are still historical documents which should be supported. It sounds like you want to force change (and specifically change in the direction of what more common languages do), as opposed to "accomodate" it. i would say that making software more flexible to handle more unusual things actually "accomodates innovation" in all languages the software supports. The more things you can support, instead of requiring everything to work the same, the more you are actually accommodating innovation.
