According to this and this information, pylas is outdated and superseded by laspy 2.0.
In contrast to the early laspy 1.x versions, laspy 2.x can be easily installed with pip. Therefore, I think it is safe to replace pylas with laspy 2.0.
Edit: There are a few cases where loading a point cloud worked only with laspy 2.0, but not with pylas (e.g. here).
