I just pushed a couple of fixes [1] for older Phobos versions and 
stdx-allocator now works down until 2.072.2.
If someone needs an older Phobos version to work with 
stdx-allocator, please let me know.
Also switching to stdx-allocator is rather easy, e.g.:

```
sed -i "s/std[.]experimental/stdx/g" **/*.d
```
