Modification of SAP Delivered BSPs

Hello all.

I have a question regarding modification of standard SAP delivered BSPs.

We are preparing to implement the LSO (Learning) solution in mySAPERP 2005. The LSO solution is delivered using BSPs. One of the requirements is to change the BSPs. In the process of investigating this, I noticed that when I go into SE80, I can change a BSP page without a key from OSS. Also, the modification assistant is not shown as with other ABAP programs.

Could anyone explain to me whether it was intended for SAP to support modifications to BSP Pages?

Thanks for your help.
