Definately not, every non trivial RISC OS application does this.

Its historically for simple progarms that don't perform any memory
management, and just use what they are given. A min value for the lowest
amount they can sensibly work with, and a max for typical usage if the Wimp
has it available. Generally now all programs use the same value for min and
max which is enough for them to start, then they claim additional workspace
at run time.
