Short description of error

Related to #80730

If some of your addons is using bgl module then you'll get up to 100 deprecation warning messages in the console like below.

Is it really necessary to have that many messages? Users might miss some more important warnings or errors behind that wall of warning. Perhaps it should be 1 warning per addon or something like that?
Is it possible to add some clarification to the warning message which addon is actually using the bgl module and producing the warnings?

Deprecation warning message:

Way to reproduce

Run any addon that uses bgl module or run the script below (got it from here):

import bpy
import gpu
from gpu_extras.batch import batch_for_shader
import bgl
 
vertices = [(0.0, 0.0, 0.0), (1.0, 0.0, 0.0),
    (0.0, 0.0, 0.0), (0.0, 1.0, 0.0),
    (0.0, 0.0, 0.0), (0.0, 0.0, 1.0)]
shader = gpu.shader.from_builtin('3D_SMOOTH_COLOR')
col = [(1.0, 0.0, 0.0, 1.0), (1.0, 0.0, 0.0, 1.0),
    (0.0, 1.0, 0.0, 1.0), (0.0, 1.0, 0.0, 1.0),
    (0.0, 0.0, 1.0, 1.0), (0.0, 0.0, 1.0, 1.0)]
batch = batch_for_shader(shader, 'LINES', {"pos": vertices, "color": col})
 
def draw():
    bgl.glLineWidth(5)
    shader.bind()
    batch.draw(shader)
    bgl.glLineWidth(1)
 
draw_handler = bpy.types.SpaceView3D.draw_handler_add(draw, (), 'WINDOW', 'POST_VIEW')
 
for area in bpy.context.window.screen.areas:
    if area.type == 'VIEW_3D':
        area.tag_redraw()
