  Writing a compiler requires implementing complex data structures
  (like symbol tables) and managing memory. If students have no prior
  programming experience, they must learn basic control flow, data
  structures, memory management and compiler theory simultaneously.
  This creates a steep learning curve, even with a simplified language.

  The claim that transitioning to C or C++ later "has not been a
  problem" is the most debatable point. While learning concepts
  first is beneficial, C requires a deep understanding of hardware
  interaction, manual memory management, and pointers - areas where
  students taught via idealized languages frequently struggle.
[What language to teach first is an old and insoluble problem.  When
I was in school most places started with Pascal while MIT started
with Lisp.  That meant they were dealing with interesting data
structures and introspection while we were still explaining how
big to make an array. -John]
