I can't believe this hasn't been filed yet, but I haven't found any related ticket, so here we go:
Steps to Reproduce:
1. Tools > Macros > Organize Macros > Libreoffice Basic
2. Click 'Libreoffice Macros' in the tree-list on the left
3. In the same tree-list, pick a macro from any of those system-wide modules, for example Gimmicks.Autotext
(it is important to try with system-wide macros and not with user-defined or document-specific ones, otherwise you won't see the misfeature)
4. Click 'Edit'
5. Try to edit the source code
Nothing happens. Macro is read-only. That wouldn't be an issue, but user really has no way of knowing that this is the case.
A yellow-ish info bar ("this document is read-only") would appear, just like for normal documents. Or it would be indicated in another suitable way that it is futile to try to edit this macro

yeah, cool, isn't it ;)
Proposed patch here:
With this patch the Basic IDE will inform that a read-only module/dialog is read-only in two ways:
1) In the status bar, after the module/dialog name by adding a "(Read-only") string to the name
2) When an alphanum key is pressed in the code editor (the message appears only in the first time per module)
Rafael Lima committed a patch related to this issue.
It has been pushed to "master":
tdf#106731 Warn user that a module/dialog is read-only in Basic IDE
It will be available in 7.6.0.
The patch should be included in the daily builds available at
https://dev-builds.libreoffice.org/daily/ in the next 24-48 hours. More

Affected users are encouraged to test the fix and report feedback.
