RSECT is used to mark that a section is intended to be read-only, so using it instead of CSECT provides a little additional information to the reader even when RENT checking is also being done for CSECT. Apart from that, I don't see any particular point in using it with RENT. For HLASM, the RSECT statement is primarily used to allow RENT checks to be selectively applied to read-only sections when using NORENT, allowing CSECT to be used for modified sections (for example when the CSECT contains an initial value which will be copied into dynamically acquired storage). If you are assembling for Linux, sections defined with RSECT will be marked as read-only but CSECT sections will be marked as read/write (unless you use the "R" option of the ASMAXT2E exit to mark all control sections as read-only).
